Title: Fuel flow anti-interruption

Abstract: An anti-flow interruption system is configured to provide a supply of fuel in the event of a fuel flow interruption from a fuel tank. The anti-flow interruption system includes a reservoir, a reservoir conduit, and a vapor bleed system. The reservoir conduit has an end disposed at the bottom of the reservoir and another connected to a fuel pump. The vapor bleed system includes a vapor bleed conduit and a vapor bleed restrictor. One end of the vapor bleed conduit is attached to the top of the reservoir and the other end is connected to the fuel pump. The vapor bleed restrictor is disposed in the vapor bleed conduit between the fuel pump and the reservoir. If fuel flow is interrupted and results in vapor being present in the reservoir, liquid fuel remaining in the reservoir continues to be supplied to the fuel pump while the vapor bleed system removes the vapor.
